Does the gap balance technique really elevate the joint line in total knee arthroplasty? A single-center, randomized study

While ATJL measurements in TKA showed similar results with GB and MR techniques, the amount of release may have caused the significantly higher JL elevation in the GB group in TTJL measurements. Based on these findings, we suggest that radiographic JL measurements on both the tibial and femoral sides in TKA may provide a more accurate assessment and we recommend to measure JL from the femoral side.
